In the figure,ABC is congruent to ADC . If the square ABCD is dilated by a factor of 2 to form A'B'C'D', the ratio of the area of A'B'C'D' to the area of ABCD is 1/2. Since the dilation is by a factor of 2, so the area of the A'B'C'D' should be smaller than the area of ABCD.

Answer:
9.2 cm
Step-by-step explanation:
The arc length is given by ...
s = rθ . . . . . where r is the radius, and θ is the central angle in radians
Here, we have ...
s = (7.9 cm)(66.4/180π) = 7.9·66.4·3.14/180 cm ≈ 9.2 cm
Arc length CD is about 9.2 cm.
Answer:
discriminant: 4; number of real roots: 2
Step-by-step explanation:
The coefficients a, b and c of this quadratic are {-3, -2, 0}.
Thus, the discriminant b^2 - 4ac is (-2)^2 - 4(-3)(0), or 4.
Because the discriminant is positive, this quadratic has two real, unequal roots.
-3p^2 - 2p can be factored as follows: -p(3p + 2). If we set this expression equal to zero, we can find the roots: {-2/3, 0}
